A policeman spots a thief 120 m ahead, immediately the policeman starts chasing the thief. The policeman runs 26 m in a minute and the thief runs 20 m in a minute. In what time will the policeman catch the thief?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 20 min.
Speed of the policeman = 26m/min
Speed of the thief = 20m/min
Relative speed = 26 - 20 = 6m/min
Time = Distance/Speed
Time = 120/6 = 20 min
